A quasi-balun circuit for receiving an unbalanced input and providing signals to a balanced-input low noise amplifier (LNA) is provided. Notably, this quasi-balun circuit can provide a phase difference between the positive and the negative terminals of the LNA that is greater than 90 degrees, but less than 180 degrees. In one embodiment, the quasi-balun circuit can provide a phase difference of approximately 135 degrees. To provide this functionality, the quasi-balun circuit includes a passive, reactive network coupled between the unbalanced input and the LNA.
